The power behind Chevrolet's winning COPO Camaro program is the factory-engineered racing engines tailored for NHRA's Stock and Super Stock classes. Those engines are now available from Chevrolet Performance for racers to use in homebuilt COPO Camaros and other race cars.
The COPO crate engines include a naturally aspirated 427 engine (7.0L) - the same displacement as the original COPO Camaros from 1969 - and two supercharged 327 (5.3L) engines - one using an LSX iron block with a 2.9L supercharger and the other using an LSX iron block and 4.0L supercharger. Both of the supercharged engines use Whipple twinscrew blowers.
The engines are built to specifications to make them eligible for competition in Stock and Super Stock. Chevrolet Performance engineers designed and tested the engines with the same methods used to develop our production and race engines, ensuring their performance and durability.

This is the most powerful supercharged COPO crate engine available. It is designed for NHRA's ''A'' Super Stock class and uses a large, 4.0L compressor to generate tremendous horsepower. Its foundation is the sturdy LSX cylinder block, with a tough, all-forged rotating assembly and the big-displacement Whipple blower. Like the other COPO crate engines, this one uses the high-flow LSX-LS7 6-bolt heads to move as much air as possible.
